The system does not restart immediately when the TEMPERATURE SETTING button is returned to its former position after pushing. It does not restart immediately because one of its safety devices actuates to prevent the system from being overloaded. The system will turn on again automatically after three minutes. The system does not start when the display shows " " (EXTERNAL CONTROL ICON) and it flashes for a few seconds after pressing an operation button. This is because the system is controlled or disabled by another controller with a higher priority. When the display flashes, it indicates that the system cannot be controlled by this indoor unit. The system does not start immediately after the power supply is turned on. Wait one minute until the micro computer is prepared for operation. The outdoor unit has stopped. This is because the room temperature has reached the set temperature. The unit switches to fan operation. " " (EXTERNAL CONTROL ICON) is displayed on the remote controller and the actual operation is different from the remote controller setting. For multi split models, the micro computer executes the following control depending on the operation mode of other indoor units. - Before you start to operate, the other indoor unit(s) is (are) already operating. When the operation mode of this unit is different from your choice, the indoor unit of your room may be put in waiting condition. (Fan: Stop, Horizontal flap: Horizontal position) ■ When humidity is high during cooling operation (In oily or dusty places). If the inside of an indoor unit is extremely contaminated, the temperature distribution inside a room becomes uneven. It is necessary to clean the inside of the indoor unit. Ask your Daikin dealer for details on cleaning the unit. This operation requires a qualified service person. ■ When the system is changed over to HEATING OPERATION after DEFROST OPERATION. Moisture generated by DEFROST becomes steam and exits. Noise of air conditioners ■ A ringing sound is heard after the unit is started. This sound is generated by the tempearture regulator operation. It will quiet down after about a minute. ■ A continuous low "hissing" sound is heard when the system is in COOLING or DEFROST OPERATION. This is the sound of refrigerant gas flowing through both indoor and outdoor units. ■ A "hissing" sound which is heard at the start or immediately after the stop of operation or which is heard at the start or immediately after the stop of DEFROST OPERATION. This is the noise of refrigerant caused by flow stop and flow change. ■ A continuous low "swishing" sound is heard when the system is in COOLING OPERATION or at a stop. The noise is heard when the drain pump is in operation. ■ A "squeaking" sound is heard when the system is in operation or after the stop of operation. Expansion and contraction of plastic parts caused by temperature change makes this noise. Dust from the units ■ Dust may blow out from the unit after starting operation from long resting time. Dust absorbed by the unit blows out. The units give off odours Operation mode Your room White mist comes out of a unit ■ Other room(s) Cooling Dry Fan only Cooling O O O W The liquid crystal display of the remote controller shows " Dry O O O W ■ Fan only O O O W W W W O Heating Heating The unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them. " Happens immediately after the main power supply switch is turned on. Shows that the remote controller is in normal condition. Continues temporarily. O: your unit can operate W: your unit in waiting mode - - ■ When the total cooling capacity of all indoor units which are operating is beyond the capacity limit of the outdoor unit, your indoor unit will be put in waiting condition. (Fan and horizontal flap: Same as setting: (cooling only model only)) After cooling mode operation of the unit of your room, when other unit(s) start to operate, the unit of your room may operate as follows: Fan: L tab, Horizontal flap: Horizontal position. The fan speed is different from the setting. Pressing the fan speed contol button does not change the fan speed. When the room temperature reaches the set temperature in heating mode, the capacity supply from the outdoor unit has stopped and the indoor unit operates in fan only mode (L tab). In case of multi split, the indoor unit alternately operates fan stop and fan only mode (L tab). This is to prevent the cool air from being blown directly onto anyone present in the room.
